Preconception Care to Reduce the Risks of Overweight and Obesity in Women of Reproductive Age: An Integrative Review

A Scoping Review of Barriers and Facilitators for Preconception Care: Lessons for Global Health Policies and Programs

Preconception care (PCC) encompasses a set of actions taken before pregnancy to support the health and well-being of women before conception to improve maternal and child health (MCH) outcomes. The utilization of PCC services is influenced by multifaceted factors that can either enable or impede women's capacity to access and utilize them effectively. This scoping review examines the barriers and facilitators influencing the utilization of PCC services among women of reproductive age (15-49 years) at both individual and community levels. Through an extensive review of published articles from 2004 to 2021, including peer-reviewed sources, barriers and facilitators were identified. At the individual level, barriers included limited knowledge about PCC, neglect of self-health, and financial constraints. Community-level barriers encompassed insufficient supply of supplements, restricted access to health care, high health care costs, and setbacks due to delayed delivery of MCH services. Conversely, individuals reported that credible sources of information, such as friends, family, and community health volunteers, facilitated their engagement with PCC services. At the community level, facilitators included government-regulated supply chains for supplements and the involvement of community workers in health monitoring. Understanding and addressing these factors can help improve the utilization of PCC services among women of reproductive age (WRA) and improve MCH outcomes.

Addressing inequalities and improving maternal and infant outcomes: the potential power of nutritional interventions across the reproductive cycle

Maternal nutrition is essential for optimal health and well-being of women and their infants. This review aims to provide a critical overview of the evidence-base relating to maternal weight, obesity-related health inequalities and dietary interventions encompassing the reproductive cycle: preconception, pregnancy, postnatal and interpregnancy. We provide an overview of UK data showing that overweight and obesity affects half of UK pregnancies, with increased prevalence among more deprived and minoritised ethnic populations, and with significant health and cost implications. The existing intervention evidence-base primarily focuses on the pregnancy period, where extensive evidence demonstrates the power of interventions to improve maternal diet behaviours, and minimise gestational weight gain and postnatal weight retention. There is a lack of consistency in the intervention evidence-base relating to interventions improving pregnancy health outcomes, although there is evidence of the potential power of the Mediterranean and low glycaemic index diets in improving short- and long-term health of women and their infants. Postnatal interventions focus on weight loss, with some evidence of cost-effectiveness. There is an evidence gap for preconception and interpregnancy interventions. We conclude by identifying that interventions do not address cumulative maternal obesity inequalities and overly focus on individual behaviour change. There is a lack of a joined-up approach for interventions throughout the entire reproductive cycle, with a current focus on specific stages (i.e. pregnancy) in isolation. Moving forward, the potential power of nutritional interventions using a more holistic approach across the different reproductive stages is needed to maximise the benefits on health for women and children.

Randomized controlled trial of prepregnancy lifestyle intervention to reduce recurrence of gestational diabetes mellitus

BACKGROUND

Preconception lifestyle intervention holds potential for reducing gestational diabetes mellitus, but clinical trial data are lacking.

OBJECTIVE

This study aimed to determine the effects of a prepregnancy weight loss intervention on gestational diabetes mellitus recurrence in women with overweight/obesity and previous gestational diabetes mellitus.

STUDY DESIGN

A 2-site, randomized controlled trial comparing a prepregnancy lifestyle intervention with educational control was conducted between December 2017 and February 2022. A total of 199 English- and Spanish-speaking adults with overweight/obesity and previous gestational diabetes mellitus were randomized to a 16-week prepregnancy lifestyle intervention with ongoing treatment until conception or educational control. The primary outcome was gestational diabetes mellitus recurrence. Analyses excluded 6 participants who conceived but did not have gestational diabetes mellitus ascertained by standard methods.

RESULTS

In the 63 (33%) women who conceived and had gestational diabetes mellitus ascertained (Ns=38/102 [37%] intervention vs 25/91 [28.0%] control; P=.17), those in the intervention group had significantly greater weight loss at 16 weeks compared with controls (4.8 [3.4-6.0] vs 0.7 [-0.9 to 2.3] kg; P=.001) and a greater proportion lost ≥5% of body weight (50.0% [17/34] vs 13.6% [3/22]; P=.005). There was no significant difference in the incidence of gestational diabetes mellitus recurrence between the intervention (57.9% [ns=23/38]) and the control group (44.0% [ns=11/25]; odds ratio, 1.8 [0.59-5.8]). Independent of group, greater prepregnancy weight loss predicted 21% lower odds of gestational diabetes mellitus recurrence (odds ratio, 0.79 [0.66-0.94]; P=.008). A ≥5% weight loss before conception reduced the odds of gestational diabetes mellitus recurrence by 82% (odds ratio, 0.18 [0.04-0.88]; P=.03).

CONCLUSION

Lifestyle intervention produced considerable prepregnancy weight loss but did not affect gestational diabetes mellitus rates. Given that the conception rate was 50% lower than expected, this study was underpowered.

Knowledge, attitudes and behaviours surrounding preconception and pregnancy health: an Australian cross-sectional survey

OBJECTIVE

To understand Australian women's knowledge, attitudes and behaviours surrounding preconception and pregnancy health and their preferences for information about these periods.

DESIGN

Cross-sectional survey.

SETTING

Making healthy changes can optimise preconception and pregnancy outcomes. Clinical practice guidelines inform preconception and pregnancy care in Australia. Women often have access to multiple sources of information on reproductive and pregnancy health.

PARTICIPANTS

Women of reproductive age were asked to complete a web-based survey. The survey development was informed by preconception guidelines, consensus statements and the national pregnancy care guidelines. The survey was distributed through social media, local and national networks from 2017 to 2018.

RESULTS

Completed surveys were received from 553 women.The majority (80.4%) had high educational attainment. Checking immunisation status and ensuring good mental health were rated as equally important actions both preconception (65%) and during pregnancy (78%). Limiting sedentary activities was not rated as an important action to take either preconception (36%), or during pregnancy (38%). Although women have good knowledge about the impact of weight on their own health outcomes (eg, gestational diabetes), there was less knowledge about adverse outcomes for babies like stillbirth and preterm birth. Women access many sources for reproductive health information, however, the most trusted source was from healthcare professionals.

CONCLUSION

Most women of reproductive age in Australia have knowledge of the key health recommendations for preconception and pregnancy. However, there are gaps related to lifestyle behaviours particularly connected to weight gain and outcomes for babies. There is a strong preference to receive trusted information from healthcare providers through multiple resources.

Pre-Pregnancy Excess Weight Association with Maternal Sociodemographic, Anthropometric and Lifestyle Factors and Maternal Perinatal Outcomes

Background: Pre-pregnancy excess weight is an important factor for adverse maternal perinatal outcomes; however, data for Greek women remain limited. Therefore, the aim of the present work was to evaluate the relation between pre-pregnant weight status and sociodemographic, anthropometric and lifestyle factors and maternal perinatal outcomes. Methods: In the present cross-sectional study, 5133 healthy women were enrolled from nine different Greek regions after applying specific inclusion and exclusion criteria. Validated questionnaires were used to assess the sociodemographic characteristics and certain lifestyle factors of the study population. Anthropometric and clinical data were retrieved from medical history files of the women, including measured weight in the first weeks of pregnancy and right before delivery, and maternal perinatal outcomes. Women's weights and heights were also measured 2–5 years postpartum by trained nutritionists. Non-adjusted and adjusted statistical analysis was performed to assess whether pre-pregnancy weight status was associated with sociodemographic, anthropometric and lifestyle factors and maternal perinatal outcomes. Results: In pre-pregnancy, 17.5% of the women were overweight, and 4.9% were classified as obese. These rates were increased 2–5 years postpartum, reaching 21.0% for overweight and 9.6% for obese women. Pre-pregnancy overweight/obesity were associated with older maternal age, higher prevalence of overweight/obesity at 2–5 years postpartum and nonexclusive breastfeeding, as well as increased rates for preterm birth and pregnancy-induced hypertension after multiple adjustments. Conclusions: Overweight and obesity rates were high among women of childbearing age in Greece. These findings highlight the urgent need for healthy lifestyle promotion and targeted obesity prevention and intervention schemes among women of reproductive age.

Which factors play a role in the decision of mothers to participate in child follow-up examinations after participation in an RCT?: a semi-quantitative study

OBJECTIVES

To determine which factors contribute to the decision of mothers to participate with their child in follow-up (FU) examinations after participation in a randomised controlled trial (RCT) prior to conception.

DESIGN

A cross-sectional survey, including Likert-scale items. Comparisons will be made between respondents who participated in all FU rounds of data collection and those who did not participate in any FU round with their child.

PARTICIPANTS

Women who participated in an RCT investigating the effect of a preconception lifestyle intervention (LIFEstyle study: Netherlands Trial Register: NTR1530) were invited to participate with their child in three FU data collections when the child had a mean age of 4.2 years, 4.6 years and 6.5 years, respectively. FU rounds included a health questionnaire, physical examination and cardiac assessment, successively.

RESULTS

Sixty-seven respondents were included, of whom 7 (10%) did not participate in any FU round and 24 (36%) participated in all FU rounds. Women who participated with their child in all 3 FU data collection rounds felt more involved in the FU research (95.8%) and agreed more often that the FU was introduced well (91.7%) as compared with women that did not participate in any FU data collection round with their child (14.3% and 28.6%, respectively). Participants of FU rounds more often agreed that participation felt like a health check for their child as compared with non-participants. In addition, participants of the physical examination and cardiac assessment more often let their decision to participate depend fully on their child, as compared with non-participants (39.4% vs 17.7% and 52.5% vs 24%, respectively).

CONCLUSIONS

To increase participation rates in future FU studies of children after maternal participation in an RCT, we suggest to involve women in the design of the FU study, to emphasise possible perceived benefits of participation and to encourage women to actively involve their child in the decision of participation.
